Application October 4, 1944, Serial No. 557,097

4 Claims.

This invention relates to roofing clips for fastening shingles together and has for its object to provide a clip which can be made economically and which can be installed with greater speed than any clip now being used in the trade.

The principal object of the invention is to provide a roofing clip made of spring material and so shaped that its ends can be spread by the fingers of an installer. Upon release by the installer the clip will securely grip the shingles snared by it so that the usual operation of hammering the clip is obviated. This not only saves the operation of hammering but saves damage to the shingles as is caused by too much or misdirected hammer blows.

Other objects and advantages will become hereinafter more fully apparent as reference is had to the accompanying drawings in which my invention is illustrated and in which:

Figure 1 is a plan view of shingles held together, in part by my clip.

Figure 2 is a perspective view of my improved clip, and

Figure 3 is a vertical section taken along the line 3-3 of Figure 1.

More particularly, l indicates my improved roofing clip which is generally of U-shape, the lower branch or leg 2 of which has greater length than the upper branch or leg 3. These two branches are joined by an intermediate or shoulder portion 4 and the upper branch is overformed so that the vertical distance between the branches is greatest adjacent the shoulder Q. In other words, the planes of the branches converge in the direction of the free ends of the branches. The upper branch 3 is provided with a single penetrating prong 5 which is obtained by punching out two sides of a triangle, the unpunched side being substantially parallel to the outer edge of the upper branch so that the point of the prong 5 may incline toward the shoulder portion l. The prong should be near the outer edge of the leg, as illustrated. The clip 5 is made of spring ma terial which may be steel plated to resist rust, spring brass or copper,

To install this clip the free end of the branch 2 is inserted under one edge of the lower of two shingles 6 and l to be locked together. The operator or installer spreads the legs 2 and 3 and pushes the clip I so that the shoulder 4 contacts the edges of both shingles. He then releases the leg 3, preferably with a snapping action so that the prong 5 will penetrate one or both of the two shingles. It is not expected that the pron will penetrate all types of shingles by a simple snap 2 of the clip at the moment of installation but the clip is always under spring tension and penetration will result by subsequent slight relative movement of the shingles and at any time when the sun warms and softens the material of the shinles.

While I have illustrated only one method of applying shingles this clip is suitable for use in all of the various ways and patterns of laying shingles in which clips are conveniently used and they are also equally applicable to use with roll roofin materials and in other fields where the problem is essentially the same as in roofing.

I therefore desire to be extended protection according to the scop of the following claims.

What I claim is:

l. A roofing clip generally of U shape with the branches of the U convergent in the direction of their free ends, one of said branches being adapted to underlay one shingle, the other of said branches being adapted to overlay a second shingle, said clip being made of spring stock whereby it maintains said shingles in continuous pressure contact.

2. A roofing clip generally of U-shape which is composed of spring stock, one branch of the U being longer than the other and fiat, the other branch being over-formed so that the branches converge at their free ends, the longer of said branches being adapted to underlay one shingle, the shorter of said branches being adapted to overlay a second shingle, one of the branches having a penetrating prong extending toward the other branch, said branches being urged toward each other by the springiness of said material when the two shingles are inserted between said branches thereby forcing said prong into penetrating engagement with at least one of said shingles.

3. A roofing clip generally of U-shape which is composed of spring stock, one branch of the U being longer than the other and flat, the other branch being overformed so that, the branches converge at their free ends, the longer of said branches being adapted to underlay one shingle in fiat contacting engagement therewith, the other of said branches being adapted to overlay a second shingle, the upper of said branches having a penetrating pron formed from the material thereof near the outer end thereof, said branches exerting pressure by reason of being made of spring stock to causesaid prong to penetrate into at least one of said shingles to a depth such that said upper branch is in surface contact with the upper of said shingles.

converge at their free ends, said one branch being 5 adapted to underlay one shingle, said other branch being adapted to overlay a second shingle, the upper of said branches having a penetrating prong formed from the material thereof near the .outer end thereof, said prong being of triangular shape with one side of the triangle paralleling the outer edge of its branch and of a length such that it penetrates both of said shingles under the.

action of the springiness of said material.
